VRSPM uses these no. to diffrentiate between players client version which makes it able to server right resource pack to right client.

What is use of protocol version no.(in VRSPM)?

Use of Protocol no.

resource-packs:
  pack-1_21:
    name: "<gradient:#55ff55:#aaffaa>Modern Pack (1.21+)</gradient>"
    url: "UR_DIRECT_DOWNLOAD_LINK" # Example URL
    hash: "" # Optional 40-character hex SHA-1 (leave empty to skip validation)
    min-protocol: 767 # 1.21
    max-protocol: 775
    gui-icon: "DIAMOND"
    slot: 11
    lore:
      - "<gray>Optimized for Minecraft <green>1.21</green> and newer.</gray>"
      - "<gray>Includes high-resolution textures and 3D models.</gray>"
      - ""
      - "<green>✔ Compatible with your client version</green>"

In the above example, i have a resource pack which is supported for 1.21-26.1.2

protocol version no. of-

1.21= 767

26.1.2= 775

Therefore all the players having client versions between 21.1-26.1.2 ( and including them) will be able to see & apply the resource pack While out dated or newer clients will be seeing a barrier block (currently)

    url: "UR_DIRECT_DOWNLOAD_LINK" # Example URL
    hash: "" # Optional 40-character hex SHA-1 (leave empty to skip validation)
    min-protocol: 767 # 1.21
    max-protocol: 9999
    gui-icon: "DIAMOND"
    slot: 11
    lore:

What could be expected in next versions?

Minor bug fix- (warning that this server uses resource packs.)
lang directory- (currently all the msg are included in the config.yml)
Automatic application of compatible rp for 1st time. (till this version player have to select rp for 1st time but after that they will automatically be applied)
